How do you guys typically delete files on Linux OS? I am thinking of using the unlink function call, but I wonder if you have a better idea, as the C++ standard has no mention of file deletion operation and it is system dependent.
Yep — the C++ standard leaves this stuff up to the OS, so if you’re on Linux (or any POSIX system),
unlink()is what you’ve got.The C standard provides
remove(), which you could try, but keep in mind that its behavior is unspecified for anything other than a ‘regular file’, so it doesn’t really shield you from getting into platform-specific filesystem details (links, etc).If you want something higher-level, more robust, and more portable, check out Boost Filesystem.
